For the thesis we developed a video display controller with FPGA circuit. For the development of the circuit we used a development board Arty from Artix FPGA family.
In the first phase we described the various standards for displaying, and then in details HDMI standard. HDMI standard is based on the technology TMDS transmission data. In details we described TMDS technology, coding and decoding algorithm. We made an additional module with HDMI connector to link the FPGA and the screen. In the thesis we briefly described the difference between the VHDL programming language and the Verilog. A video display controller was developed in Xilinx development environment in the VHDL programming language. We divided the digital circuit of encoder into two segments, namely TMDS encoder and RGB signal generator. We tested the functioning of the circuit with a development board Arty connected to the screen via HDMI and the HDMI cable. To check the functioning of graphics, we can individually adjust RGB signals.
